What is the primary function of skeletal muscle?

The primary function of skeletal muscle is to provide movement of bones. Skeletal muscles are attached to the skeleton and are responsible for voluntary movements, allowing for actions such as walking, running, lifting, and various other physical activities. This muscle type is conducive to movement because it can contract and relax in response to voluntary signals from the nervous system, thus enabling precise control over movement.

In contrast, other choices relate to different muscle types or functions. Pumping blood is the primary function of cardiac muscle, while involuntary movements are facilitated by smooth muscle in organs. Lastly, regulating digestive processes is a role played by smooth muscle, not skeletal muscle, which does not regulate involuntary functions. Therefore, the focus on the skeletal muscle's role in the voluntary movement of bones makes it clear that providing movement is its primary function.
